The act of lighting one's own fart on fire with means of a lighter or other open flame (when abnormally bored, high, drunk, stupid, etc.) causing a small flame to catch for a quick second. Can be done with pants on, or pants off; pants off usually results in singed ass, gooch, genital hairs, you were warned.

He flofed a huge one, but in the end, his gooch hairs were completely burnt.
